Appending date in FileName - Vb.net

Question

I have got this

FileName = "Events_Data.csv"

I want to add date to this, so output required is

FileName = "Events_Data_20140521.csv"

I have got data in separate variables, just don't know how to add this before .csv in the file name.

Can anyone please help.

Regards

Solution 1

Chech below code

VB.Net

Dim FileName As String = "Events_Data.csv"
FileName = FileName.Replace(".csv", "_" & System.DateTime.Now.ToString("yyyyMMdd") & ".csv")

C#.Net

string FileName = "Events_Data.csv";
string ptest =System.DateTime.Now.ToString("yyyyMMdd");
FileName = FileName.Replace(".csv", "_" + ptest  + ".csv");

Solution 2

Dim FileName As String = "Your File Name"
FileName += DateTime.Now.ToString("ddmmyyyyHHmm") + _
            System.IO.Path.GetExtension(FileUpload1.FileName)

FileUpload1.SaveAs(Server.MapPath("Upload/" + FileName))
FileName = "Upload/" + FileName

I need to write this in C# and this System.DateTime.Now.ToString("yyyyMMdd") will be a variable. Can you help.

Can you please provide a brief explanation.

this should be DateTime.Now.ToString("ddMMyyyyHHmm") otherwise it will give you minutes, not months :)
